Patent DE-2031499-A1 (DE)
Title: Ceramic glaze dipping - with accelerated workpiece removal motion
IPC: B28B11/04
Filed: 1970-06-25
Abstract: Immersion device for the glazing of ceramics consists of a glazing basin through which the articles dipped travel in a parabolic path, this being effected by arms, which are radially attached to a vertical revolving disc. The arms take hold of the plates, which have been made to slide into the basin, accelerating each relative to the disc prior to its transfer to a removal device on leaving the bath. The accelerating movement of the arms is effected as the result of their being springloaded, a cam controlling their locking and releasing. The acceleration motion ensures that all excess glaze is removed from the plate on their emergence from the glazing bath.

Title: Non-returnable package coffee filter - with two compartments for holding different types of coffee
Inventor: MICHIELSEN FRANCISCUS
IPC: B65D81/00
Filed: 1973-10-24
Abstract: Filter consists of a conical envelope, made from a suitable plastic material, which has 3 annular shoulders. These carry the filter discs mounted so that, in conjunction with the envelope, they form 2 chambers. Each disc is sealed at its edges to the corresp. shoulder. The roasted and ground coffee is introduced into the 2 chambers, using, for example, a coffee of the same mix but with a more lightly roasted one in the lower compartment. The filter provides a rich extract from comparatively cheap coffee and with an appreciable redn. in the percolation time. In coffee machines, rich extracts are obtd. with filters of limited dimensions. It is known that a lightly roasted coffee is very rich in volatile aromatic substances and that a strongly roasted coffee is rich in solid water-sol. aromatic substances; the combination of the 2 in 1 filter results in a partic. rich extract. However, the two compartments may contain coffee which differs in other respects, such as in compsn. and/or in the fineness of grind.
